DIE FOR MAKING CLI'P K lNG-BOLLTS.

SPECIFICATION forming part of Letters Patent No. 270,404, dated January 9, 1883.

Application filed September 15, 1882. (No model.) t

To all whom tmay concern Be it known that I, NICHOLAS EcoLEs, of Auburn, in the county of Cayuga and State of New York, have invented la new and useful Improvement in Dies for Making Clip King- Bolts, ol' which the following is a full, clear, and exact description. A

rThis invention relates to the manufacture of clip king-bolts for vehicles; and it consists in dies of a novel construction for making clip king-bolt forgings, whereby a king bolt of superior finish is produced at a greatly reduced cost, substantially as hereinafter described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in a ll the figures.

Figures l and 2 are inside face' views ofmy improved dies; Fig. 3, a longitudinal section ofthe same on the lille a' in Figs. land 2; and Fig. 4, a transverse section thereofon the line y y in Fig. 3. Figs. 5 and 6 are side and edge views ol the iron blank or bleakdown in its proper shape for introduction within the dies lo make a completeA king-bolt forging. F|g. 7 is a face view of the forging after being struck up in the dies froth the blank or breakdown without rehearing, as hereinafter described. Fig. b is a face view of the forging as exhibited 'in Fig. 7 after the titl has been trimmed ott', and as ready to be pres-ed into proper shape; and Flg.9 isaviewin perspective of a tinished clip kmgbolt ready for cutting the screw-thread ou its pins or titles.

The kingl bolt forging represented in Fig. 9 co.|sistsof the usual unes, b b, on which screwvthreads are to be cut for the nuts, which hold the bolt in place. spread and flattened wings c c constituting the clip partof the bolt at the crotch of thetines, a shouldel'or bead, d, which forms the supporting-surface of the bolt, a bearing portion, e, and the usual stem portion,f.

The dies A B are formed with` recesses b b for the titles, ar convex portion, c', in the top die, A, and corresponding concave, c2, in the bottom die, B, for the clip part c cot' the bolt; also, recesses d ef for the shoulder d, and bearing and stem portions @fof the bolt.

'lhe blank or breakdown shown in Figs. 5 and 6 is' produced from a square bar of iron, which, as it 1s taken from thet'urnace, is struck or forged into the required shape, and is afterward placed, during the same heat, with its broadest sides or faces downward and uppermost in the die B, the portion C of it lying in the part c2 of said die7 and the portions D E F, respectively, in or over the recesses d. ef. Said blank contains more metal thanis required to fill the dies, and consequently tins g are. left on the forging formed from the blank by the dies, as shown in Fig. 7, which [ius are alterward removed, as, shown in Fig. 8, and the trimmed forging subsequently bent and pressed to its required shape. The shape of the blank or breakdown serves to fill the dies by distributing the metal evenly. Repeated blows are given to the top die belore the blank in the lower die or between the dies is brought to thc form represented in Fig. 7; but it is done at one and the same heat that was necessary to produce the breakdown, thus saving time, labor, and fuel,and reducing waste. TheA action of the dies is such that the king-bolt may be said to be completed when struck by the die. rlhns it is spread and finished dat on the inside laces of the clip partc c, the shoulder d. is formed, and the clip-bolt is forged to the proper thickness all at one and the same heat, and the bolt left ready, after the tin has been removed, to press into the required shape lo tit or attach to any axle.

The dies used to tllus produce a clip kingbolt forging essentially differ in their construction from other. dies which have been employed to make a mere king-holt blank, and

.trom which the finished blanks are dropped lu a pile and allowed to cool, their taken to a press and the tins trimmed'off, and said blanks afterward rehealed, the .titles spread open and forged into shape by another pair of dies, and the blanks, which have been left with their clip ends spread widely open, again heated, the crotch ofthe clip flattened to couform with the insides of the tines, and the tines straightened into shape. All this labor is avoided by my improved dies, which produce a complete lorging instead of a mere blank.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The dies A B, constructed and combined for producing the forging represented in Fig. 7, from which, after trimming a completed kingbolt forging, as shown in Fig. 9, is made essentially as herein described.

NICHOLAS ECOLES.
